According to the reports, nearly three dozen NFL players entered the competition and were coached by Steelers linebacker James Harrison and retired (for now) Seahawks running back Marshawn Lynch.

Dolphins receiver Kenny Stills, 49ers linebacker NaVorro Bowman and Raiders punter Marquette King were some of the named players who attended the event.

With the news of the Raiders’ eventual move to Vegas, this won’t be the only time the NFL’s gambling policy is tested.

“We did not change any of our gambling policies in the context of the Raiders relocation,” NFL commissioner Roger Goodell said during his press conference at the owners meetings last month. “It wasn’t necessary and the Raiders didn’t ask us to do that. We don’t see changing our current policies.”
